BACKGROUND OF THE INVENTION AND RELATED ART STATEMENT

The present invention relates to an image reading apparatus and a network system.

In a conventional network system, an image reading apparatus such as a copier, a facsimile, a scanner, a multi function product (MFP) and the like is connected through a network. For example, a multi function product and personal computers as a plurality of terminal devices are connected through a network.

In the conventional network system, the multi function product reads an image of an original in a push scanning mode, so that it is possible to transmit image data of the image of the original to a specific personal computer among the personal computers. In this case, a storage unit of the multi function product stores a transmission destination list, and the transmission destination list registers information for identifying each personal computer, i.e., terminal information, as a transmission destination. When the transmission destination list is displayed on a display unit of the multi function product, an operator selects the specific personal computer of the transmission destination in the transmission destination list, so that the image data are transmitted to the specific personal computer thus selected. (Refer to Patent Reference)

Patent Reference: Japanese Patent Publication No. 2000-59553

In the conventional network system described above, it is not possible to transmit the image data to a personal computer whose terminal information is not registered in the transmission destination list. Further, when a personal computer is newly connected to the network and terminal information thereof is registered in the transmission destination list, it is necessary to obtain acknowledgment of an administrator of each personal computer. Accordingly, an operation of registering the terminal information becomes cumbersome. Further, when acknowledgment of an administrator is not obtained, it is not possible to register the terminal information of the personal computer in the transmission destination list.

In view of the problems described above, an object of the present invention is to provide an image reading apparatus and a network system capable of solving the problems of the conventional network system. In the present invention, it is possible to transmit image data to a personal computer whose terminal information is not registered in a transmission destination list.

Further objects and advantages of the invention will be apparent from the following description of the invention.

FIG. 10 is a schematic view No. 2 showing another example of the detail information stored in the storage unit 17 of the multi function product 11 according to the first embodiment of the present invention. FIG. 11 is a schematic view No. 3 showing a further example of the detail information stored in the storage unit 17 of the multi function product 11 according to the first embodiment of the present invention.

An operation of the multi function product 11 will be explained first. When an image of an original is transmitted to the personal computer p1 as a specific one of the personal computers p1, p2, and p3 from the multi function product 11 through the network 13, the operator places the original on an original placing stage (not shown) disposed on the multi function product 11. Then, the operator operates the operation unit 16 to input the terminal information of the personal computer p1 as the transmission destination to which the image is transmitted. Further, the operator touches a specific operation element of the operation unit 16 to input a push scan request for requesting the multi function product 11 to transmit read data as the image data acquired with the reading unit 20 to the personal computer p1. The read data and the image data constitute image information.

In the embodiment, the terminal information is set in advance for identifying each of the personal computers p1, p2, and p3. The terminal information is represented with specific characters of each of the personal computers p1, p2, and p3, and is formed of a text as shown in FIG. 6.

In the next step, a reading processing unit of the main control unit 15 performs a reading processing. When the terminal information and the push scan request are input, the reading control unit 21 scans the original to start reading the image of the original.

In the next step, an information request processing unit of the main control unit 15 performs an information request processing. Accordingly, the communication control unit 18 transmits an information acquisition request to each of the personal computers p1, p2, and p3 to request specific information through the concurrent notification and the terminal information input by the operator through the operation unit 16.

In the next step, the main control unit 15 starts a timer disposed therein to start measuring a period of time. Accordingly, for a specific period of time, the main control unit 15 waits for a response as answer information from each of the personal computers p1, p2, and p3 with respect to the information acquisition request.

When the main control unit 15 receives the response from each of the personal computers p1, p2, and p3, a terminal device determining processing unit of the main control unit 15 performs a terminal device determining processing, so that the terminal device determining unit 19 determines the contents of the response. In particular, the terminal device determining processing unit determines whether the response thus received is a response indicating that the terminal information is matched (the terminal information thus input is matched to the terminal information of the personal computer P1 among the personal computers p1, p2, and p3).

When the terminal device determining processing unit determines that the response received from the personal computer p1 among the personal computers p1, p2, and p3 is the response indicating that the terminal information is matched, the terminal device determining processing unit stores in the storage unit 17 the response indicating that the terminal information is matched and details of the terminal information transmitted from the personal computer p1 or detail information.

As shown in FIGS. 7 and 8, the detail information includes the terminal information of the personal computer p1, a host name, an IP address, and a terminal information matching determination result. The terminal information matching determination result represents a determination result whether the terminal information is matched. The IP address is an address composed of a plurality of numbers set for identifying each of the personal computers p1, p2, and p3. The host name is a name of a server (not shown) connected through the network 13.

When the terminal device determining processing unit determines that any of the responses received from the personal computers p1, p2, and p3 is not the response indicating that the terminal information is matched, the main control unit 15 completes the process.

In the next step, when the timer becomes timeout to stop measuring a period of time, the terminal device determination processing unit determines whether the terminal information is stored in the storage unit 17.

As shown in FIG. 9, when the terminal device determination processing unit determines that the terminal information is not stored in the storage unit 17 (not registered), the terminal device determination processing unit displays a warning on the display unit of the operation unit 16 indicating that there is no personal computer with matched terminal information. Then, the terminal device determination processing unit sends an instruction to the reading control unit 21 to stop reading the image of the original (reading termination), thereby completing the process.

When the terminal device determination processing unit determines that the terminal information is stored in the storage unit 17, the terminal device determination processing unit determines whether only one personal computer has the matched terminal information.

As shown in FIG. 10, when the terminal device determination processing unit determines that only one personal computer has the matched terminal information, the one personal computer is registered as the specific personal computer having the terminal information thus matched.

In the next step, an image information transmission processing unit of the main control unit 15 performs an image information transmission processing to determine whether the image of the original is completely read. When the image information transmission processing unit determines that the image of the original is completely read, the personal computer p1 is connected to the multi function product 11 according to the IP address. Accordingly, read data of the image thus read are transmitted to the personal computer p1 as the image data, thereby completing the process.

As shown in FIG. 11, when the terminal device determination processing unit determines that a plurality of the personal computers has the matched terminal information, the main control unit 15 displays a warning on the display unit of the operation unit 16 indicating that a plurality of the personal computers has the matched terminal information. Further, the main control unit 15 sends an instruction to the reading control unit 21 to stop reading the image of the original (reading termination), thereby completing the process.

An operation of the personal computer p1 will be explained next. First, a terminal information matching determination processing unit of the main control unit 25 performs a terminal information matching determination processing. In particular, when the transmission reception unit 28 receives the information acquisition request and the terminal information from the multi function product 11, the determining unit 29 compares the terminal information transmitted from the multi function product 11 with the terminal information stored in the terminal information storage unit 27. Accordingly, the determining unit 29 determines whether the terminal information transmitted from the multi function product 11 matches to the terminal information stored in the terminal information storage unit 27.

When the determining unit 29 determines that the terminal information transmitted from the multi function product 11 matches to the terminal information stored in the terminal information storage unit 27, an answer information transmission processing unit of the main control unit 25 performs an answer information transmission processing. Accordingly, the answer information transmission processing unit sends a determination result of the terminal information matching determination processing unit as answer information to the multi function product 11.

More specifically, when the determining unit 29 determines that the terminal information transmitted from the multi function product 11 matches to the terminal information stored in the terminal information storage unit 27, the answer information transmission processing unit controls the transmission reception unit 28 to transmit a response indicating that the terminal information matches and the detail information of the personal computer p1 to the multi function product 11.

When the determining unit 29 determines that the terminal information transmitted from the multi function product 11 does not match to the terminal information stored in the terminal information storage unit 27, the answer information transmission processing unit controls the transmission reception unit 28 to transmit a response indicating that the terminal information does not match to the multi function product 11, thereby completing the process.

When the answer information transmission processing unit controls the transmission reception unit 28 to transmit the response indicating that the terminal information matches to the multi function product 11, the multi function product 11 transmits the image data to the personal computer p1. Accordingly, an image information reception processing unit of the main control unit 25 performs an image information reception processing. More specifically, the transmission reception unit 28 receives the image data. After the transmission reception unit 28 receives the image data, the image data thus received are stored in the image data storage unit 30, thereby completing the process.

As described above, in the embodiment, when the operator simply inputs the terminal information in the multi function product 11, it is possible to automatically transmit the image data to the personal computer with the unregistered terminal information. Accordingly, it is possible to improve operability of the multi function product 11. Further, it is possible to prevent the image data from inadvertently being transmitted to personal computers other than the personal computer p1 as the transmission destination.

The flow charts shown in FIGS. 2 and 3 will be explained next. In step S1, the terminal information of the personal computer p1 is input. In step S2, the push scan request is input. In step S3, the reading control unit 21 scans the original to start reading the image of the original. In step S4, the communication control unit 18 transmits the information acquisition request and the terminal information.

In step S5, the main control unit 15 starts the timer. In step S6, it is determined whether the timer becomes timeout. When it is determined that the timer becomes timeout, the process proceeds to step S10. When it is determined that the timer does not become timeout, the process proceeds to step S7.

In step S7, it is determined whether the response is received from one of the personal computers p1, p2, and p3. When it is determined that the response is received from one of the personal computers p1, p2, and p3, the process proceeds to step S8. When it is determined that the response is not received from one of the personal computers p1, p2, and p3, the process returns to step S6.

In step S8, it is determined whether the response thus received is the response indicating that the terminal information is matched. When it is determined that the response thus received is the response indicating that the terminal information is matched, the process proceeds to step S9. When it is determined that the response thus received is not the response indicating that the terminal information is not matched, the process returns to step S6.

In step S9, the terminal information of the personal computer p1 is stored in the storage unit 17, and the process returns to step S6. In step S10, it is determined whether the terminal information of one of the personal computers p1, p2, and p3 is stored in the storage unit 17. When it is determined that the terminal information of one of the personal computers p1, p2, and p3 is stored in the storage unit 17, the process proceeds to step S13. When it is determined that the terminal information of one of the personal computers p1, p2, and p3 is not stored in the storage unit 17, the process proceeds to step S11.

In step S11, the warning is displayed on the display unit of the operation unit 16 indicating that there are not the personal computers p1, p2, and p3. In step S12, the instruction is sent to the reading control unit 21 to stop reading the image of the original, thereby completing the process.

In step S13, it is determined whether there is only one personal computer. When it is determined that there is only one personal computer, the process proceeds to step S16. When it is determined that there is a plurality of the personal computers, the process proceeds to step S14. In step S14, the warning is displayed on the display unit of the operation unit 16 indicating that there is a plurality of the personal computers. In step S15, the instruction is sent to the reading control unit 21 to stop reading the image of the original, thereby completing the process. In step S16, the multi function product 11 waits until the image of the original is completely read. In step S17, the image data are transmitted to the personal computer p1, thereby completing the process.

The flow chart shown in FIG. 4 will be explained next. In step S21, the transmission reception unit 28 waits until the transmission reception unit 28 receives the information acquisition request and the terminal information from the multi function product 11. In step S22, the determining unit 29 compares the terminal information transmitted from the multi function product 11 with the terminal information stored in the terminal information storage unit 27.

In step S23, the determining unit 29 determines whether the terminal information transmitted from the multi function product 11 matches to the terminal information stored in the terminal information storage unit 27. When the determining unit 29 determines that the terminal information transmitted from the multi function product 11 matches to the terminal information stored in the terminal information storage unit 27, the process proceeds to step S25. When the determining unit 29 determines that the terminal information transmitted from the multi function product 11 does not match to the terminal information stored in the terminal information storage unit 27, the process proceeds to step S24.

In step S24, the transmission reception unit 28 transmits the response to the multi function product 11 indicating that the terminal information does not match, thereby completing the process. In step S25, the transmission reception unit 28 transmits the response to the multi function product 11 indicating that the terminal information does match. In step S26, the transmission reception unit 28 waits until the transmission reception unit 28 receives the image data. In step S27, the image data are stored in the image data storage unit 30, thereby completing the process.

Second Embodiment

A second embodiment of the present invention will be explained next. Components in the second embodiment similar to those in the first embodiment are designated with the same reference numerals, and explanations thereof are omitted. The components in the second embodiment similar to those in the first embodiment provide effects similar to those in the first embodiment.

In the first embodiment, each of the personal computers p1, p2, and p3 determines whether the terminal information transmitted from the multi function product 11 matches to the terminal information of the personal computer p1. In the second embodiment, in the multi function product 11, the operator operates the operation unit 16, so that it is possible to determine whether the terminal information thus input matches the terminal information transmitted from each of the personal computers p1, p2, and p3.

FIG. 12 is a block diagram showing a network system according to the second embodiment of the present invention. In this case, the terminal information matching determination processing unit of the main control unit 25 controls the terminal device determining unit 19 to determine whether the terminal information thus input through the operation unit 16 by the operator matches the terminal information transmitted from each of the personal computers p1, p2, and p3.

An operation of the network system with the configuration described above will be explained next. FIG. 13 is a flow chart No. 1 showing an operation of the multi function product 11 according to the second embodiment of the present invention. FIG. 14 is a flow chart No. 2 showing the operation of the multi function product 11 according to the second embodiment of the present invention.

FIG. 15 is a flow chart showing an operation of the personal computer p1 according to the second embodiment of the present invention. FIG. 16 is a schematic view showing an operation sequence of the network system according to the second embodiment of the present invention.

FIG. 17 is a schematic view showing an example of a response from the personal computer p1 according to the second embodiment of the present invention. FIG. 18 is a schematic view showing an example of detail information stored in the storage unit 17 of the multi function product 11 according to the second embodiment of the present invention.

An operation of the multi function product 11 will be explained first. When the image of the original is transmitted to the personal computer p1 as a specific one of the personal computers p1, p2, and p3 from the multi function product 11 through the network 13, the operator places the original on the original placing stage (not shown) disposed on the multi function product 11. Then, the operator operates the operation unit 16 to input the terminal information of the personal computer p1 as the transmission destination to which the image is transmitted. Further, the operator touches a specific operation element of the operation unit 16 to input the push scan request for requesting the multi function product 11 to transmit the read data as the image data acquired with the multi function product 11 to the personal computer p1. The read data and the image data constitute the image information.

In the next step, the reading processing unit of the main control unit 15 performs the reading processing. When the terminal information and the push scan request are input, the reading control unit 21 scans the original to start reading the image of the original. In the next step, the information request processing unit of the main control unit 15 performs the information request processing. Accordingly, the communication control unit 18 transmits the information acquisition request to each of the personal computers p1, p2, and p3 through the concurrent notification.

In the next step, the main control unit 15 starts the timer disposed therein to start measuring a period of time. Accordingly, for a specific period of time, the main control unit 15 waits for the response as the answer information from each of the personal computers p1, p2, and p3 with respect to the information acquisition request. When the main control unit 15 receives the response from each of the personal computers p1, p2, and p3, the terminal device determining processing unit stores the detail information of the personal computers p1, p2, and p3 in the storage unit 17.

As shown in FIG. 17, the detail information includes the terminal information of the personal computer p1, the host name, the IP address, and the like.

In the next step, when the timer becomes timeout to stop measuring a period of time, the terminal device determination processing unit determines whether the terminal information is stored in the storage unit 17.

When the terminal device determination processing unit determines that the terminal information is not stored in the storage unit 17, the terminal device determination processing unit displays the warning on the display unit of the operation unit 16 indicating that there is no personal computer with the matched terminal information. Then, the terminal device determination processing unit sends the instruction to the reading control unit 21 to stop reading the image of the original (reading termination), thereby completing the process.

When the terminal device determination processing unit determines that the terminal information is stored in the storage unit 17, the terminal device determination processing unit controls the terminal device determining unit 19 to determine whether the terminal information of the personal computer p1 matches to the terminal information stored in the storage unit 17.

When the terminal device determining unit 19 determines that the terminal information of the personal computer p1 matches to the terminal information stored in the storage unit 17, the terminal device determination processing unit determines whether only one personal computer has the matched terminal information. When the terminal device determination processing unit determines that only one personal computer has the matched terminal information, the terminal device determination processing unit determines that the personal computer is the personal computer with the input terminal information.

In the next step, the image information transmission processing unit of the main control unit 15 determines whether the image of the original is completely read. When the image information transmission processing unit determines that the image of the original is completely read, the personal computer p1 is connected to the multi function product 11 according to the IP address. Accordingly, the read data of the image thus read are transmitted to the personal computer p1 as the image data, thereby completing the process.

As shown in FIG. 18, when the terminal device determination processing unit determines that a plurality of the personal computers has the matched terminal information, the main control unit 15 displays the warning on the display unit of the operation unit 16 indicating that a plurality of the personal computers has the matched terminal information. Further, the main control unit 15 sends the instruction to the reading control unit 21 to stop reading the image of the original (reading termination), thereby completing the process.

An operation of the personal computer p1 will be explained next. First, when the transmission reception unit 28 receives the information acquisition request from the multi function product 11, the answer information transmission processing unit of the main control unit 25 sends the detail information to the multi function product 11.

When the multi function product 11 transmits the image data to the personal computer p1, the image information reception processing unit of the main control unit 25 performs the image information reception processing, so that the transmission reception unit 28 receives the image data. After the transmission reception unit 28 receives the image data, the image data thus received are stored in the image data storage unit 30, thereby completing the process.

As described above, in the embodiment, the multi function product 11 is configured to determine whether the terminal information matches to the terminal information transmitted from each of the personal computers p1, p2, and p3. Accordingly, it is possible to eliminate the determining unit 29 in each of the personal computers p1, p2, and p3. As a result, it is possible to reduce work load applied to each of the personal computers p1, p2, and p3.

The flow charts shown in FIGS. 13 and 14 will be explained next. In step S31, the terminal information of the personal computer p1 is input. In step S32, the push scan request is input. In step S33, the communication control unit 18 transmits the terminal information acquisition request. In step S34, the reading control unit 21 scans the original to start reading the image of the original. In step S35, the communication control unit 18 transmits the information acquisition request.

In step S36, the main control unit 15 starts the timer. In step S37, it is determined whether the timer becomes timeout. When it is determined that the timer becomes timeout, the process proceeds to step S40. When it is determined that the timer does not become timeout, the process proceeds to step S38.

In step S38, it is determined whether the response is received from one of the personal computers p1, p2, and p3. When it is determined that the response is received from one of the personal computers p1, p2, and p3, the process proceeds to step S39.

FIG. 30 is a schematic view No. 2 showing another example of the detail information stored in the storage unit 17 of the multi function product 11 according to the third embodiment of the present invention.

An operation of the multi function product 11 will be explained first. When the image of the original is transmitted to the personal computer p1 as a specific one of the personal computers p1, p2, and p3 from the multi function product 11 through the network 13, the operator places the original on the original placing stage (not shown) disposed on the multi function product 11. Then, the operator operates the operation unit 16 to input the terminal information of the personal computer p1 as the transmission destination to which the image is transmitted, and input and specify the image format. Further, the operator touches a specific operation element of the operation unit 16 to input the push scan request for requesting the multi function product 11 to transmit the read data as the image data acquired with the multi function product 11 to the personal computer p1. The read data and the image data constitute the image information.

In the embodiment, the terminal information is set in advance for identifying one of the personal computers p1, p2, and p3. The terminal information is represented with specific characters of each of the personal computers p1, p2, and p3, and is formed of a text as shown in FIG. 26. The image format is a format for performing the image conversion on the read data of the image read with the reading unit 20 to the specific image data in the multi function product 11. The operator operates the multi function product 11 to input and specify the specific image format.

In the next step, the reading processing unit of the main control unit 15 performs the reading processing. When the terminal information and the push scan request are input, the reading control unit 21 scans the original to start reading the image of the original. In the next step, an image conversion processing unit of the main control unit 15 performs an image conversion processing. Accordingly, it is determined whether it is possible to perform the image conversion to the image format thus specified with the image conversion unit 22.

In the embodiment, the image conversion unit 22 includes the support image format table as an image format information table shown in FIG. 27. The image conversion processing unit refers to the support image format table, and determines whether the image format specified by the operation is stored in the support image format table. When the image conversion processing unit determines that the image format thus specified is stored in the support image format table, the image conversion processing unit determines that it is possible to perform the image conversion to the image format thus specified.

In the next step, when the image conversion processing unit determines that it is possible to perform the image conversion to the image format thus specified, the information request processing unit of the main control unit 15 performs the information request processing. Accordingly, as shown FIG. 24, the communication control unit 18 transmits the terminal information and the information acquisition request to each of the personal computers p1, p2, and p3 through the concurrent notification.

When the image conversion processing unit determines that it is not possible to perform the image conversion to the image format thus specified, as shown in FIG. 25, the main control unit 15 transmits the terminal information, the information acquisition request and the image format thus specified to each of the personal computers p1, p2, and p3, so that the main control unit 15 determines whether each of the personal computers p1, p2, and p3 supports the image format (whether it is possible to perform the image conversion to the image format thus specified).

In the next step, the main control unit 15 starts the timer disposed therein to start measuring a period of time. Accordingly, for a specific period of time, the main control unit 15 waits for the response as the answer information from each of the personal computers p1, p2, and p3 with respect to the information acquisition request. When the main control unit 15 receives the response from each of the personal computers p1, p2, and p3, the terminal device determining processing unit of the main control unit 15 performs the terminal device determining processing, so that the terminal device determining unit 19 determines the contents of the response. In particular, the terminal device determining processing unit determines whether the response thus received is the response indicating that the terminal information is matched (the terminal information thus input is matched to the terminal information of the personal computer P1 among the personal computers p1, p2, and p3).

When the terminal device determining processing unit determines that the response received from the personal computer p1 among the personal computers p1, p2, and p3 is the response indicating that the terminal information is matched, the terminal device determining processing unit stores in the storage unit 17 the response indicating that the terminal information is matched and the detail information of the terminal information transmitted from the personal computer p1. The detail information includes the terminal information of the personal computer p1, the host name, the IP address, and the terminal information matching determination result.

In the embodiment, when the communication control unit 18 transmits the terminal information and the image format thus specified as well as the information acquisition request to the personal computer p1 through the concurrent notification, as shown in FIGS. 28 and 29, the detail information includes the terminal information of the personal computer p1, the host name, the IP address, the terminal information matching determination result, an image format support determination result, the image format supported on the personal computer p1, and the like. The image format support determination result represents a determination result whether the personal computer p1 supports the image format.

When the terminal device determining processing unit determines that any of the responses received from the personal computers p1, p2, and p3 is not the response indicating that the terminal information is matched, the main control unit 15 completes the process.

In the next step, when the timer becomes timeout to stop measuring a period of time, the terminal device determination processing unit determines whether the terminal information is stored in the storage unit 17.

When the terminal device determination processing unit determines that the terminal information is not stored in the storage unit 17, the terminal device determination processing unit displays the warning on the display unit of the operation unit 16 indicating that there is no personal computer with the matched terminal information. Then, the terminal device determination processing unit sends the instruction to the reading control unit 21 to stop reading the image of the original (reading termination), thereby completing the process.

When the terminal device determination processing unit determines that the terminal information is stored in the storage unit 17, the terminal device determination processing unit determines whether only one personal computer has the matched terminal information. As shown in FIGS. 28 and 29, when the terminal device determination processing unit determines that only one personal computer p1 has the matched terminal information, the terminal device determination processing unit determines that the personal computer p1 is the personal computer with the input terminal information.

In the next step, the image conversion processing unit determines whether the image of the original is completely read. When the image conversion processing unit determines that the image of the original is completely read, the multi function product 11 determines whether it is possible to perform the image conversion to the image format thus specified.

In the next step, when the multi function product 11 determines that it is possible to perform the image conversion to the image format thus specified, the image conversion processing unit controls the image conversion unit 22 to perform the image conversion on the read data to the image data with the image format thus specified. Then, the image information transmission processing unit connects the personal computer p1 to the multi function product 11 according to the IP address. Further, the image information transmission processing unit transmits the image data thus converted to the personal computer p1, thereby completing the process.

When the multi function product 11 determines that it is not possible to perform the image conversion to the image format thus specified, the main control unit 15 refers to the detail information and determines whether the personal computer p1 can perform the image conversion to the image format thus specified.

As shown in FIG. 28, when the personal computer p1 can perform the image conversion to the image format thus specified (the image format support determination result is yes), and the detail information is stored in the storage unit 17, the image information transmission processing unit connects the personal computer p1 to the multi function product 11 according to the IP address. Further, the image information transmission processing unit transmits the read data to the personal computer p1, and notifies the image format thus specified to the personal computer p1, so that the image information transmission processing unit instructs the personal computer p1 to convert to the image data with the image format thus specified.

As shown in FIG. 29, when both the multi function product 11 and the personal computer p1 cannot perform the image conversion to the image format thus specified (the image format support determination result is no), the terminal device determination processing unit displays the warning on the display unit of the operation unit 16 indicating that it is not possible to convert to the image format thus specified. Then, the terminal device determination processing unit sends the instruction to the reading control unit 21 to stop reading the image of the original (reading termination), thereby completing the process.

As shown in FIG. 30, when the terminal device determination processing unit determines that a plurality of the personal computers has the matched terminal information, the terminal device determination processing unit displays the warning on the display unit of the operation unit 16 indicating that a plurality of the personal computers has the matched terminal information. Further, the terminal device determination processing unit sends the instruction to the reading control unit 21 to stop reading the image of the original (reading termination), thereby completing the process.

An operation of the personal computer p1 will be explained next. First, the terminal information matching determination processing unit of the main control unit 25 performs the terminal information matching determination processing. When the transmission reception unit 28 receives the information acquisition request, the terminal information and the image format from the multi function product 11, the determining unit 29 compares the terminal information transmitted from the multi function product 11 with the terminal information stored in the terminal information storage unit 27. Accordingly, the determining unit 29 determines whether the terminal information transmitted from the multi function product 11 matches to the terminal information stored in the terminal information storage unit 27.

Further, an image format support determination processing unit of the main control unit 25 performs an image format support determination processing. Accordingly, the image conversion determining unit 31 determines whether it is possible to perform the image conversion to the image format thus specified.

In the next step, the answer information transmission processing unit of the main control unit 25 sends a determination result of the terminal information matching determination processing unit and a determination result of the image format support determination processing unit as answer information to the multi function product 11.

More specifically, when the determining unit 29 determines that the terminal information transmitted from the multi function product 11 matches to the terminal information stored in the terminal information storage unit 27, and the image conversion determining unit 31 determines that it is possible to perform the image conversion to the image format thus specified, the answer information transmission processing unit of the main control unit 25 performs the answer information transmission processing. Accordingly, the transmission reception unit 28 sends the response indicating that the terminal information matches, the response indicating that it is possible to perform the image conversion to the image format thus specified, and the detail information of the personal computer p1 to the multi function product 11.

When the determining unit 29 determines that the terminal information transmitted from the multi function product 11 does not match to the terminal information stored in the terminal information storage unit 27, the answer information transmission processing unit controls the transmission reception unit 28 to transmit a response indicating that the terminal information does not match to the multi function product 11.

Further, when the image conversion determining unit 31 determines that it is not possible to perform the image conversion to the image format thus specified, the answer information transmission processing unit controls the transmission reception unit 28 to transmit a response indicating that it is not possible to perform the image conversion to the image format thus specified to the multi function product 11.

When the transmission reception unit 28 sends the response indicating that the terminal information matches, the response indicating that it is possible to perform the image conversion to the image format thus specified, and the detail information of the personal computer p1 to the multi function product 11, the multi function product 11 transmits the read data to the personal computer p1. Accordingly, the image information reception processing unit of the main control unit 25 performs the image information reception processing, so that the transmission reception unit 28 receives the image data.

After the transmission reception unit 28 receives the image data, the read data thus received are converted to the image data with the image format thus specified, and the image data thus received are stored in the image data storage unit 30, thereby completing the process.

When the multi function product 11 converts the read data to the image data with the image format thus specified, the multi function product 11 transmits the image data to the personal computer p1. Accordingly, the image information reception processing unit of the main control unit 25 performs the image information reception processing, so that the transmission reception unit 28 receives the image data. After the transmission reception unit 28 receives the image data, the image data thus received are stored in the image data storage unit 30, thereby completing the process.

As described above, in the embodiment, even when it is not possible to perform the image conversion to the image format thus specified in the multi function product 11, when it is possible to perform the image conversion to the image format thus specified in the personal computer p1, it is possible to transmit the read data as is to the personal computer p1.
